K8047 header file

Instruments General
1

Hi,

Im’ trying to connect my K8047 to Labview.
I found some information about the blockdiagram and what to do,
but they speak from a header or a header file from Velleman.

What does this mean? What do I have to do with this code?

Thanks

Code:
#ifdef __cplusplus
extern “C” {
#endif

#define FUNCTION __declspec(dllimport)
FUNCTION void __stdcall StartDevice();
FUNCTION void __stdcall StopDevice();
FUNCTION void __stdcall LEDon();
FUNCTION void __stdcall LEDoff();
FUNCTION void __stdcall ReadData(int *ptr);
FUNCTION void __stdcall SetGain(int Channel, int Gain);

#ifdef __cplusplus
}
#endif

Please see in this example how the function prototype for the function ReadData is entered to LabVIEW:
